Abstract: 1,160,329. Hand-driven wiping pads. EUROPEAN ATOMIC ENERGY COMMUNITY. 26 June, 1967 [27 June, 1966], No. 29384/67. Heading A4K. Apparatus for taking samples of radioactive contamination from a surface includes a reel indexing mechanism, for renewing a paper wiping surface from a roll, and manual means for moving the wiping surface in a circular path, in contact with the contaminated surface. The used section of paper is preferably wound on a take-up reel (39) and the paper has a detachable impervious film, on one side, to prevent radio-active matter from being transferred between adjacent turns of the take-up roll. In order to take a sample from a suspectedly contaminated surface, the open mouth of bell 9 is pressed thereagainst and handle 26 is depressed one or more times, to cause hollow shaft 7 to rotate and carry the assembly, including reels 38, (39), platen 47, roller (45) and gong (51) in a circular path. Spring 34 urges the assembly downwardly, so that platen 47 exerts the required pressure on the test surface. The used section of the paper is changed, by pulling out cord 64. This rotates pulley 61 and gears 36, (44) driving the reels 38, (39). When a fresh section of paper is located, under platen 47, a striker (52) is operated, by a pin (54), to sound a gong (51). On release, cord 64 is returned by spring (65), while reels 38, (39) are held against reverse rotation, by no-back pawls (59, 60) engaging ratchets (43, 42).

Abstract: 1511887 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 15 July 1975 [23 July 1974] 29587/75 Heading H4K Matching units AT for converting speech band data signals into a form suitable for providing a display on a television set are provided in a telephone exchange between a concentrator CE 1  and an expansion unit CE 2  the inputs to the concentrator and outputs from the expansion units being connected via switches to n subscribers lines. A subscribers telephone set TL, Fig. 3, is coupled via switch C and wires ab of line L to an exchange CT to which data centres CD are also coupled. To gain access to a data centre a subscriber TD, dials a predetermined number and a connection to a data centre CD, is established in known manner. The data centre then transmits a tone which is detected by a tone detector RT, to cause a control unit CA to allocate a matching unit AT to the connection and to complete a connection from the subscribers line 1 via a matching unit AT to the data centre CD 1 . The insertion of the matching unit in the connection reverses the polarity at line wires ab of the subscriber station to forward bias diodes D 1 , D 2  and energize a Zener diode power supply to the stations data circuitry. A control device CC is energized to operate a changeover switch C of the telephone set TL and to connect the aerial socket of a commercial television set TV to the output of a RF modulator MO whose frequency is in the VHF or UHF band of the television set. If a monitor type TV set is used the modulator MO is omitted and the TV set input is connected directly via a synch regenerator RS to a receiver R 1  Once the matching unit has been inserted in the connection it sends a signal to the data centre which responds by transmitting information which is converted into a display format in the matching unit before being transmitted to the TV set for display. PCM is used for the TV display signals transmitted from the matching unit to the subscriber station. The subscriber selection signals are transmitted by line current variations of a decadic form. The initial display is normally address information indicating the addresses to be signalled by the subscriber to gain access to various types of information. The subscriber then dials the required address which is received by the matching unit where it is convened into the display format and returned to the subscriber station for display. Having checked the address on the display, the subscriber sends a transmission code signal which causes the matching unit to send the selected address to the data centre. The required data is then sent from the data centre to be displayed at the subscriber station.
